Arsene Wenger is warning Chelsea not to take the title for granted just yet after Arsenal showed the "pride of champions" to delay the Blues' coronation for at least another five days.

The Gunners' 1-0 Highbury win against Tottenham last night, courtesy of Jose Antonio Reyes' 22nd-minute strike, ensured that Chelsea must now win at Bolton on Saturday to make certain of their first title in 50 years.

The Blues need two points from their remaining four games but Wenger sounded a note of defiance in declaring that Jose Mourinho's side could struggle to win at the Reebok Stadium.

The Arsenal boss said: "We have the pride of defending champions and real champions fight for as long as there is the slightest chance, whereas other people give up.

"As long as we have a one per cent chance, we will carry on trying. Chelsea have not won at Bolton yet. I think it will be very difficult for them there. You can never choose too much when you win the title, you win it when you can.

"They have a Champions League game against Liverpool tomorrow night so it won't be easy. Bolton are a difficult side to play and can beat anyone on their day."

Wenger praised Reyes, whose strike was only his second Premiership goal since October 2 after a lean spell over the winter.

"He missed an early chance but after he scored, he was a different animal on the pitch. That gave him the boost he needed," said Wenger.

However, Wenger expressed frustration at Chelsea's trip to Old Trafford having been postponed due to the FA Cup semi-finals, ensuring that they will not face Manchester United until the final week.

"If Chelsea had had to play their game at Old Trafford before they faced us, the championship would maybe not be over. That would have made things much more difficult," he added.

"I don't want to take anything away from Chelsea, they deserve to be where they are.

"But the biggest trophy in the country is the Premier League so it's difficult to understand why those fixtures have to change for a secondary trophy. It's been an advantage to Chelsea."

Wenger played down one moment of controversy at Highbury, when Lauren's elbow made contact with Erik Edman's neck as they chased the ball into touch early in the second half.

Spurs boss Martin Jol was more frustrated that his side failed to snatch a last-gasp equaliser when Robbie Keane headed narrowly wide, while Spurs also unsuccessfully claimed a late handball by Ashley Cole.

Meanwhile, Wenger has confirmed that Thierry Henry is a doubt for the FA Cup final.

Wenger revealed a scan had at least shown no serious long-term problems but that the French striker is still a doubt for the May 21 showpiece in Cardiff.

Wenger, who is also still without Freddie Ljungberg, added: "Their scans were positive and they have both made progress but they are still in pain."

West Brom will be aiming to leap out of the bottom three tonight when they take on rejuvenated Blackburn Rovers at the Hawthorns.

The Baggies' recent revival was halted by Saturday's 4-0 defeat by Boro, although former Riverside supremo Robson believes Steve McClaren's side were flattered by the scoreline.

Robson said: "I want to put that game behind us. I've got to lift the players for an important game. We must make sure we don't just bounce back as far as the performance is concerned, but also in terms of winning.

"Saturday was a little bit of a blow for the lads because everything during the last two months has been going well for us.

"When you do get a knock-back it's all about how you respond to it and I'm expecting a really good response from the players.

"They have lifted themselves after knock-backs in the past this season and have got straight back on with the job. I am sure they will put in a good performance tonight."
